When graphene is placed on a crystalline surface, the periodic structures within the layers
superimpose and moiré superlattices form. Small lattice rotations between the two materials
in contact strongly modify the moiré lattice parameter, upon which many electronic,
vibrational, and chemical properties depend. While precise adjustment of the relative
orientation in the degree-and sub-degree-range can be achieved via careful deterministic
transfer of graphene, we report on the spontaneous reorientation of graphene on a metallic …
